ABSTRACT:
In a method for determining motion vectors for each of the plurality of image blocks (X, O) together constituting a television image, motion vectors are computed only for selected ones (X) of the image blocks, and motion vectors for the remaining ones (O) of the image blocks are interpolated at least in part from the computed motion vectors of the selected blocks.
